Air pressure manifold for valve repair

Apparatus for use in the repair of different types of multi-cylinder internal combustion engines by admitting air under pressure into selected cylinders of the engine to seat all the corresponding valves, comprising

• a manifold member including an inlet fitting for connection to a source of compressed air,
• at least two primary outlet fittings on said manifold,
• at least two primary spark plug hole fittings,
• primary hoses connecting each of said primary outlet fittings to a corresponding one of said hole fittings to provide at least two primary air circuits,
• at least one secondary outlet fitting on said manifold including a normally closed check valve,
• at least one secondary spark plug hole fitting and a secondary hose connected thereto at one of the hose ends and a nipple fitting on the other hose end adapted to interlock with and open the associated check valve,
• whereby the apparatus can be used in the repair of a variety of engines by simultaneously pressurizing the selected cylinders as repairs are made.
